Schritt 4: Code
Der Code finden Sie unten und benötigen Sie eine modifizierte Arduino IDE, mit dem ein LinkIt Board Code hochladen zu arbeiten.
Dies ist nur ein Beispiel-Code, wodurch den Motor drehen in entgegengesetzte Richtungen.
int enA = 10; int in1 = 9; int in2 = 8; // motor two int enB = 5; int in3 = 7; int in4 = 6; void setup() { // set all the motor control pins to outputs pinMode(enA, OUTPUT); pinMode(enB, OUTPUT); pinMode(in1, OUTPUT); pinMode(in2, OUTPUT); pinMode(in3, OUTPUT); pinMode(in4, OUTPUT); } void demoOne() { // this function will run the motors in both directions at a fixed speed // turn on motor A digitalWrite(in1, HIGH); digitalWrite(in2, LOW); // set speed to 200 out of possible range 0~255 analogWrite(enA, 200); // turn on motor B digitalWrite(in3, HIGH); digitalWrite(in4, LOW); // set speed to 200 out of possible range 0~255 analogWrite(enB, 200); delay(2000); // now change motor directions digitalWrite(in1, LOW); digitalWrite(in2, HIGH); digitalWrite(in3, LOW); digitalWrite(in4, HIGH); delay(2000); // now turn off motors digitalWrite(in1, LOW); digitalWrite(in2, LOW); digitalWrite(in3, LOW); digitalWrite(in4, LOW); } void demoTwo() { // this function will run the motors across the range of possible speeds // note that maximum speed is determined by the motor itself and the operating voltage // the PWM values sent by analogWrite() are fractions of the maximum speed possible // by your hardware // turn on motors digitalWrite(in1, LOW); digitalWrite(in2, HIGH); digitalWrite(in3, LOW); digitalWrite(in4, HIGH); // accelerate from zero to maximum speed for (int i = 0; i < 256; i++) { analogWrite(enA, i); analogWrite(enB, i); delay(20); } // decelerate from maximum speed to zero for (int i = 255; i >= 0; --i) { analogWrite(enA, i); analogWrite(enB, i); delay(20); } // now turn off motors digitalWrite(in1, LOW); digitalWrite(in2, LOW); digitalWrite(in3, LOW); digitalWrite(in4, LOW); } void loop() { demoOne(); delay(1000); demoTwo(); delay(1000); }
